Procedure

In 100 ml of an aqueous solution containing 1.0 g of cis-epoxysuccinic acid and 0.44 g of magnesium hydroxide and adjusted to pH value of 8.0, a 0.5 g portion of clean microbic cells of Acetobacter curtus No. 4 (FERM-P No. 2879) obtained by following the procedure of Example 3 was added and shaken at 35° C for 5 hours. In the reaction mixture, there was formed magnesium L(+)-tartrate. The amount of the salt thus produced was 1.19 g and the yield was 91 percent. By treating this product with a column packed with Amberlite IR 120 (H+ type cation-exchange resin) similarly to Example 3, there was obtained L(+)-tartaric acid. This L(+)-tartaric acid was found to have an optical purity of 100 percent.
